SPECIFICATION forming part of` Letters Patent No. 251,702, dated January3, 1885?..`

Application filed April 25, 1881.

To all whom it may concern Beit known thatI, MATYAS GZiNER, acitizen ofthe United States ofAmei-ica, residentof the city, county, and State ofNew York, have iuvented certain new and useful Improvements in Lamps,which improvementsA are fully set forth in the following specification,reference being had to the accompanying drawings, in which- Figure I isa vertical section of a lamp embodying my invention, and Fig. Il is avertical section ofthe burner.

Similar letters indicate corresponding parts.,

My invention relates to that class ot reservoir-lamps in which theoil-supply chamber is, by means ofa continuous siphon action, also bythe operation of a oat-valve, rendered independent of the main reservoiras to the level of oil in the latter.

The object of my improvements is to construct a lamp-body such as willadmit, in proportion to the size of its feed-receptacle, any desirednumber of arms and burners, shall be applicable to chandelier, bracket,or table, and, owing to its peculiar form, size, andcompactness, shallbe especially adapted for use in articles ofornament, bijoutry,statuettes, figures,

signs, Src.

Safety from eplosion is ordinarily sought to be attained by preventingthe accumulation of oil in the vicinity of the flame. I, however, whilemore ,perfectly isolating the oil and its vapors from places oflignition, seek to insure greater safety by the` process of refining theoil previous to its entering the supply-chamber, said process beingcarried on in the reservoir of the lam p-body itself.

In the drawings, the letterAdesignates the spherical lamp-body, havingan opening, a, closed by a screw-plu g, for the admission ofoil, andcontaining, compactly arranged, the shaft B,fastened to the main body atboth its ends;

and within said shaft the supplyftube D,which latter has iioatin g valveE E, and is connected with the reservoir by siphon i It vIt is aperforated partition or false botto upholdingthe metallic filter andretiner S, composed of pulverized and `.tell-mixed asbestus, carbonizedserpentine rock, and bone-black.

The secondary parts, outside of the spherical reservoir-to wit, neck C,feed-pipe G, feed-re- (No model.)

M is the outer case of the mineral cone orY wick, is made of metal,andhas an internal perforated flange, T, to catch the solid impuritiesof the lame, said impurities being consumed thereon by the intense heatto which they are exposed. This conic frustum is movably attached to theburner I, to which it is similar in form, and admits ofa verticalsliding on said burner, so that by drawing it up or down the volume offlame may be respectively contracted or enlarged at will.

O is the terminal portion of arm El,one'for tieth of an inch indiameter.

The operation is as follows: The oil filling the reservoir, afterbecoming purified and refined by percolation through the metalliciilterS, is taken up from the bottom of the reservoir by siphon Nrising,wherein, under hydrostatic pressure to the top ot' thesupply-tube D, it descends into said tube until the float-valve, risingwith the liquid, closes the opening b, preventing thereby the furtherentrance ofthe oil. When, however, owing to the consumption of oil bythe burners, the level of the liquid in the supply-tube D is lowered,the ioat, descendingwith thefallingliquid,uncovers theopening forrenewed supply of oil, until the reservoir A is entirely exhausted. Thenal passage of the oil through G, F, and H into I and its finalconsumption at the points of the mineral conc require no explanation.

I claim and desire to obtain Letters Patent for;-

1. The combination, with the lamp-body, of an interior closed chamberconnected. with the body by a siphon having its inner end closed oropened by a ball-valve, substantially as described.

2. The combination of the external chamber or reservoir, the interior orsupply chamber, and a siphon connecting with substantially the lowestpart of the reservoir and the top of the IOO closed supply-chamber,whereby feeding of the oil will be uninterrupted at its highest andlowest level and undue accumulation of oil at the burner is prevented,substantially as described.

3. The combination ofthe lamp-body having the shaft B with thesupply-chamber and the Siphon.

4. The burner I, containing the air-pipe K, surrounded by a mineral concserving as e Wick, substantially as set forth.

5. The combination, with the burner, ofthe conic frustum M, having aninternal perforated ange to catch the solidv impurities of the laine andcapable of sliding vertically upon the burner, substantially as and forthe purpose specified.

6. The combination, in a. lamp-body, of the chamber for the unfilteredoil above, the ilter ing device R S, and a chamber for refined andfiltered oil below, substantially as described.

7. The combination ofthe burner having the mineral cone described, thetube H, the supply-chamber D, the Siphon, and the reservoir, all 'as setforth.

In testimony that l claim the foregoing as my own I have hereto a-fiixedmy signature in presence of two witnesses.
